Safe and secure storage
PSSM - physical security and stockpile management - comprises of procedures and actions that are necessary to ensure responsible and safe accounting, storage, transportation and handling of weapons and their ammunition.
Effective PSSM enhances local, national, regional and international security as it reduces the risks of diversion, illicit trafficking, and accidental explosions.
International standards have been developed that provide guidance to state actors on the implementation of good practices in PSSM to enhance safety, security, and accountability: these include the International Ammunition Technical Guidelines (IATG) and, for small arms and light weapons, the Modular Small-arms-control Implementation Compendium (MOSAIC).
These guidelines provide detailed information and advice on topics such as weapons accounting, including inventory management, as well as technical requirements for the safe storage of weapons and ammunition. These voluntary guidelines are designed to support relevant agencies combat the threat of diversion and unintended explosions.
